The current of the earth fault.
is appox 1.7amp please verify this with book concepts of physics by h.c. verma
because i read it few year back and at present i don't have that book
A current that flows from phase conductors to earth or protective conductors etc from the point of an insulation breakdown.
What else can I help you with?
Earth fault relay and an overcurrent relay Methods to energise an earth fault relay?
Earth fault relay and an over current relay Methods to energies an earth fault relay with simulation diagram?
What is the difference between balanced earth fault and restricted earth fault?
There is such a thing as a three phase to earth fault, so maybe this is what you mean by a "balanced earth fault". I don't believe any earth or ground currents would flow in this case. A restricted earth fault is a typical phase to earth fault, where the zone of protection is restricted to a specific area, such as around a transformer. "Restricted" is referring to the protection method, not what is actually going on with the currents and voltages.
Why star connection used in transmission?
Transmission circuits are prone to earth faults.Only star connection permits flow of earth fault current and the operation of earth fault relays.
Why is sensitive earth fault protection required?
Sensitive Earth Fault protection is required to either to alarm or trip the faulted circuit. It is usually used for resistance grounded or ungrounded systems; where first earth fault doesn't interrupt supply. It is also used on long overhead lines (even solidly grounded systems) where earth fault currents can be significantly low.
Restricted earth fault protection circuit?
Restricted earth fault protection is used to protect a specific zone, and should not trip for a fault outside of that zone (usually limited to a transformer, and possibly extending to lowside, highside, and tertiary breakers).
What is an earth fault relay?
An earth fault relay is a relay that is activated by a fault current that flows from the power line to the earth. Earth fault relays are found in power distribution systems.

Is a fault is a crack in the Earth's crust?
Yes a fault is a crack in the Earth's crust
How do you calculate maximum earth fault current?
transformer max earth fault current
How does a standby earth fault relay work?
As per my openion standby earth fault relay work on zero impedance measurement, when earth fault occures than zero

What is the breaking point in the layers of earth is called?
A break in the Earth's surface might be called a chasm, a fissure, or a fault line.
What are the kinds of movements of the earth?
reverse fault, strike slip fault, and normal fault
How do you calculate 3 phase earth fault loop?
You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault. If you want the potential phase to earth fault current it will be your voltage times your impedance. If you want the phase to phase potential fault current then you should just double the above result.
What is a breaking point in layers of the earth?
That sounds like you are looking for the word "fault" or "fault line".
Break in Earth's rocks caused by stress?
Fault
Circuit diagram of stand by earth fault relay?
earth fault relay is similar like earth leakage ralay,but the 2nd one is more sensitiv.
